74LV125PW,118

Overview

The 74LV125PW,118 is a low-voltage Si-gate CMOS quad buffer and line driver manufactured by NXP USA Inc. It features four non-inverting buffers with 3-state outputs controlled by active-low output enable inputs (nOE). The device operates within a wide supply voltage range of 1.0 V to 5.5 V and is optimized for applications between 1.0 V and 3.6 V. It accepts TTL input levels when VCC is between 2.7 V and 3.6 V. The component provides ESD protection exceeding 2000 V (HBM) and 200 V (MM), ensuring robust performance in various environments.

Feature Summary

• Provides four independent non-inverting buffer/line drivers with 3-state outputs
• Wide operating voltage range from 1.0 V to 5.5 V
• High electrostatic discharge protection capability
• Compatible with TTL input levels at specific supply voltages

Applications

• Low voltage signal buffering and line driving
• Bus-oriented applications requiring high-impedance states
• TTL to CMOS level translation interfaces

Procurement Notes

Verify the package type matches the required PCB footprint, specifically TSSOP14 for this part number. Confirm the temperature range specification aligns with the target application environment, as the datasheet specifies operation from -40 °C to +125 °C. Ensure that the supply voltage constraints are strictly adhered to during design validation to prevent exceeding absolute maximum ratings.

Selection Notes

Select this component for designs requiring low-voltage operation down to 1.0 V. It serves as a pin-compatible replacement for 74HC125 and 74HCT125 devices. Consider its propagation delay characteristics relative to the system clock speed. Verify that the output current capabilities meet the load requirements of the connected circuitry without exceeding the specified limits.

Part Context

This device belongs to the 74LV series of low-voltage CMOS logic components. It is functionally equivalent to other industry-standard quad buffer parts but offers enhanced performance at lower supply voltages. The PW suffix indicates the TSSOP14 package variant, which is suitable for surface-mount assembly technologies commonly used in modern electronic manufacturing.

Replacement Considerations

The 74LV125 is pin and function compatible with 74HC125 and 74HCT125. When substituting, verify that the supply voltage requirements of the original design fall within the 1.0 V to 5.5 V range of the LV series. Ensure that the input logic levels remain compatible, particularly if transitioning from HCT to LV families.
